Definitions

  • the present invention relates to a rotating machine, such as a generator or an electric motor for wind power plant, and traction cable plant.
  • the rotating machine generally comprises a bearing, an annular stator supporting the bearing, an annular, turnable rotor facing the stator and supported by the bearing, and, connected to the rotor, a drive arrangement.
  • one of the stator or rotor will carry permanent magnets or other magnetic field generators, while the other of the stator and the rotor will carry windings, the magnetic field generators and the windings being disposed on opposing surfaces of the stator and of the rotor.
  • Embodiments preferably are particularly suited for use in an annular variety of such rotating machines in which an annular stator faces an annular rotor.
  • the rotor rotates within the stator and carries the magnetic field generators, such as permanent magnets, on an external surface of the rotor.
  • the windings or coils are carried on an inner surface of the stator facing the rotor. It should be clear that the rotor could rotate outside the stator and/or the magnetic field generators could be carried on the stator.
  • the machines are sized and arranged to enable human passage into the interior of the rotor.
  • a generator is described in the international patent application WO 2004/017497 A1 where simple mounting and dismounting of individual generator components is possible. In this case, however, only one particular arrangement of annular windings and the same armature is provided, which are disposed so as to be sequential. That is, the generator is constructed with an axial arrangement of axially-alternating rotors and stators. The rotors and stators are of similar radial dimension and are broken into segments. However, because of the axial arrangement of the components, the issue of access to the annular stator surrounding an annular rotor, or vice versa, is not addressed.
  • each rotor segment comprises at least one permanent magnet and each stator segment has at least one winding.
  • Each rotor segment preferably is disposed on a base which is provided with a profile shaped to prevent radial and circumferential motion of the segment while allowing axial movement of the segment.
  • a dovetail-shaped profile which engages the edges of the mounting slot in the rotor ring with grooves in sides of the profile can be employed.
  • each rotor segment can be removed in the axial direction without the entire rotor having to be removed.
  • the stator could instead carry magnets while the rotor could instead carry windings or coils.
  • one or more rotor segments 5 in the vicinity of the stator segment 4 is removed by sliding it axially in the mount 10 to provide access to the stator segment 4 via the opening left in the mount 10 . If the stator segment 4 must be removed, then it can be removed in a substantially radial direction (at the face) through the opening left in the mount 10 once the stator segment's restraints have been released.
